Referring initially to FIG. 3, a computing system 20 for generating a custom color scheme 40 for a web application 34 will be discussed. The custom color scheme 40 is automatically generated by a server 30 that executes a color scheme generator algorithm 32. The web application 34 may be a Software as a Service (SaaS) application, for example. Each time an update is made to the SaaS application, for example, then a new custom color scheme 40 is to be individually generated for the updated SaaS application so as to match the custom color scheme 40 in the SaaS application before the update. This automation based on the color scheme generator algorithm 32 speeds up the color customization process which is typically done by hand.

The illustrated computing system 20 includes a server 30 and at least one computing device 50. The server 30 includes the color scheme generator algorithm 32 used to determine a source set of colors 36 and a target set of colors 38. As will be explained in detail below, determination of the custom color scheme 40 to be used in the web application 34 is based on the color scheme generator algorithm 32 determining color position permutations 42, color separation distances 44 and deltas 46 between the color separation distances 44 for the different color position permutations 42.

The computing device 50 includes a browser 56 for accessing the color scheme generator algorithm 32 in the server 30. A display 54 is to display the custom color scheme 40 to be used in the web application 34. A user interface 52 is to provide user input to the color scheme generator algorithm 32 as needed.

Execution of the color scheme generator algorithm 32 for generating the custom color scheme 40 for the web application 34 includes determining a source set of colors 36 to be used in the custom color scheme 40, determining color separation distances 44 between colors in the source set of colors 36, and determining a target set of colors 38 in the web application 34.

The color scheme generator algorithm 32 determines color position permutations 42 of the colors in the target set of colors 38 that can be replaced with the colors in the source set of colors 36. For each color position permutation 42, color separation distances 44 are determined between the replaced colors. For each color position permutation 42, deltas 46 between the color separation distances in the replaced colors and the color separation distances 46 in the source set of colors 36 are determined.

The color scheme generator algorithm 32 selects one of the color position permutations 42 based on the deltas 46 being minimized with respect to the deltas 46 for the other color position permutations 42. The selected color position permutation 42 is to be used as the custom color scheme 40 for the web application 34.

The custom color scheme 40 is thus used to map the source set of colors 36 to the target set of colors 38. The color scheme generator algorithm 32 generates a custom color scheme 40 for each web page 25 within the web application 34. In real time, the color scheme generator algorithm 32 generates an application page with the original source set of colors 36 and the web page 25 in the proposed custom color scheme 40.

This is an opportunity for a user of the computing device 50 to review the appearance of both the web page 35 with the proposed custom color scheme 40 applied and the source set of colors 36. The color scheme generator algorithm 32 is configured to adjust, if needed, the colors in the proposed custom color scheme 40 based on input from the user interface.

Referring now to FIG. 4, generation of an example custom color scheme 40 for the web application 34 will be discussed. The color scheme generator algorithm 32 first determines the source set of colors 36. The source set of colors 36 may be determined a number of different ways.

One approach is for the color scheme generator algorithm 32 to analyze color schemes in a source web application. This is accomplished by crawling the source web application to analyze color schemes in dialogs that fit enterprise or corporate requirements. Another approach is to analyze the color scheme of a logo. Yet another approach is to provide a user defined color scheme to the color scheme generator algorithm 32. These approaches are examples and are not to be limiting. If the source set of colors 36 is monochrome, then execution of the color scheme generator algorithm 32 further includes generating variants of the monochrome colors so as to expand the source set of colors 36.

An example source set of colors 36 is provided in screen shot 200. The source set of colors 36 includes blue for display section 202, light blue for display section 204, and gray for display section 206. In addition, anyone of the sections may include text. For example, display section 206 may include black text with a gray background.

After the source set of colors 36 has been determined, then the color scheme generator algorithm 32 determines color separation distances 44 between colors in the source set of colors 36. The color separation distances 44 may be determined using anyone of a number of different color distance determination methods. The color scheme generator algorithm 32 may use a RGB Euclidian distance method, a Cielab Delta E method, or a color tolerance distance method, for example. These example color distance determination methods are not to be limiting as other color distance determination methods may be used by the color scheme generator algorithm 32.

Using screen shot 200 as an example, color separation distances for the source set of colors 36 are determined between display sections 202 and 204, between display sections 202 and 206, and between display sections 204 and 206. The color separation distances 44 are used by the color scheme generator algorithm 32 to determine color contrasts for the colors in the source set of colors 36. Color contrasts between the text and the background are also determined. Maintaining a similar contrast in the custom color scheme 40 that is to be applied to the web application 34 is necessary for providing a pleasant user experience.

Next, the color scheme generator algorithm 32 analyzes color schemes in the web application 34 to determine the target set of colors 38. This is accomplished by crawling the web application 34 to analyze color schemes in its dialogs. The web application 34 may also be referred to as the target web application.

An example target set of colors 38 is provided in screen shot 210. The screen shot 210 corresponds to a particular web page 35 within the web application 34. The target set of colors 38 includes red for display section 212, purple for display section 214, and white for display section 206. In addition, anyone of the sections may include text. For example, display section 216 may include black text with a white background.

After the target set of colors 38 has been determined, the color scheme generator algorithm 32 determines color position permutations 42 of the colors in the target set of colors 38 that can be replaced with the colors in the source set of colors 36. For example, one color position permutation 42 includes display section 212 being replaced by blue, display section 214 being replaced by light blue, and display section 216 being replaced by gray. A next color position permutation 42 includes display section 212 remaining blue but swapping the light blue and gray between display sections 214 and 216.

Yet another color position permutation 42 includes display section 212 being replaced by light blue, display section 214 being replaced by blue, and display section 216 being replaced by gray. A next color position permutation 42 includes display section 212 remaining light blue but swapping the blue and gray between display sections 214 and 216. Determination of the color position permutations 42 continues until all possible color combinations 42 have been determined.

For each color position permutation 42, the color scheme generator algorithm 32 determines color separation distances 44 between the replaced colors. This is similar to the color scheme generator algorithm 32 determining color separation distances between the colors in the source set of colors 36.

The color separation distances 44 for each color position permutation 42 are determined using the same color distance determination method used for determining the color separation distances 44 for the source set of colors 36. As noted above, the color separation distances 44 are used by the color scheme generator algorithm 32 to determine color contrasts for the colors in the source set of colors 36 as well as color contrasts for the colors in each of the color position permutations 42.

For each color position permutation 42, the color scheme generator algorithm 32 determines deltas 46 between the color separation distances 44 in the replaced colors and the color separation distances 44 in the source set of colors 36. The color scheme generator algorithm 32 then selects one of the color position permutations 42 based on the deltas 46 being minimized with respect to the deltas 46 for the other color position permutations 42.

As an example, if the deltas 46 between the color separation distances 44 in the replaced colors in one of the color position permutations 42 and the color separation distances 44 in the source set of colors 36 are high, then this color position permutation 42 would not provide for a pleasant user experience. The contrast between the colors as arranged in the color position permutation 42 is not comparable to the contrast of colors in the source set of colors 36.

Conversely, if the deltas 46 between the color separation distances 44 in the replaced colors in one of the color position permutations 42 and the color separation distances 44 in the source set of colors 36 are low, then this color position permutation 42 would provide for a pleasant user experience.

Based on the color separation distanced deltas 46 between each color position permutation 42 and the source set of colors 36, the color scheme generator algorithm 32 selects the color position permutation 42 having deltas 46 as close to zero as possible when compared to the deltas 46 for the other color position permutations 42. For the color position permutation 42 having the lowest deltas 46, then the contrast of the source colors as mapped into target set of colors 38 more closely matches the contrast of colors in the original source set of colors 36.

Once the color position permutation 42 has been selected, the color scheme generator algorithm 32 generates a custom stylesheet using the custom color scheme 40 corresponding to the color position permutation 42 for the web page 35. The custom stylesheet is applied a next time the web application 34 is accessed.

Since there are multiple web pages 35 in a web application, the color scheme generator algorithm 32 is configured to repeat the determining and selecting steps for each web page 35 in the web application 34. The color scheme generator algorithm 32 generates a custom stylesheet using the custom color scheme 40 for each web page 35.

In some cases, repeating the entire process each web pages 35 can introduce inconsistencies. Since most web applications are dynamic there is typically no finite set of web pages for a web application 34. Alternatively, the server 30 may be configured to inspect the multiple web pages 35 until all colors in all components of the stylesheet are mapped to the source set of colors 36 to achieve consistency over the multiple web pages.

In one approach, the color separation distances 44 as determined by the color scheme generator algorithm 32 are between all colors. Alternatively, the color separation distances 44 as determined by the color scheme generator algorithm 32 are limited to adjacent colors. Being limited to adjacent colors reduces the number of color position permutations 42.

The color scheme generator algorithm 32 is further configured to repeat the determining and selecting steps for different color distance determination methods. The computing system 50 displays the selected color position permutations 42 for each color distance determination method. Depending on which one of the color distance determination methods would provide the most pleasant user experience, as displayed, is selected to be used as the custom color scheme the selection is based on input from the user interface 40 for the web application 34 based on user input.

Referring now to the flowchart 300 in FIG. 5, a method for generating a custom color scheme 40 for a web application 34 includes from the start (Block 302) determining a source set of colors 36 to be used in the custom color scheme 40 at Block 304, and determining color separation distances 44 between colors in the source set of colors 36 at Block 306. The method further includes determining a target set of colors 38 in the web application 34 at Block 308.

Color position permutations 42 of the colors in the target set of colors 38 that can be replaced with the colors in the source set of colors 36 are determined at Block 310. For each color position permutation 42, the method includes determining color separation distances 44 between the replaced colors as Block 312. For each color position permutation 42, the method includes determining deltas 46 between the color separation distances 44 in the replaced colors and the color separation distances 44 in the source set of colors 36 at Block 314.

The method further includes at Block 316 selecting one of the color position permutations 42 based on the deltas 46 being minimized with respect to the deltas 46 for the other color position permutations 42. The selected color position permutation 42 is to be used as the custom color scheme 40 for the web application 34. The method ends at Block 318.

Another aspect is directed to a non-transitory computer readable medium for operating a server 30 to generate a custom color scheme 40 for a web application 34, and with the non-transitory computer readable medium having a plurality of computer executable instructions for causing the server 30 to perform steps that includes determining a source set of colors 36 to be used in the custom color scheme 40, determining color separation distances 44 between colors in the source set of colors 36, and determining a target set of colors 38 in the web application 34.

Color position permutations 42 of the colors in the target set of colors 38 that can be replaced with the colors in the source set of colors 36 are determined. For each color position permutation 42, color separation distances 44 between the replaced colors are determined. For each color position permutation 42, deltas 46 between the color separation distances 44 in the replaced colors and the color separation distances 44 in the source set of colors 36 are determined.

One of the color position permutations 42 is selected based on the deltas 46 being minimized with respect to the deltas 46 for the other color position permutations 42. The selected color position permutation 42 is to be used as the custom color scheme 40 for the web application 34.

 12. The method according to claim 11 further comprising replacing the colors in the target set of colors with the colors in the selected position.
 13. The method according to claim 11 wherein the target set of colors is associated with a web application, and further comprising generating a stylesheet to map the source set of colors to the target set of colors based on the colors in the selected position, with the stylesheet being applied a next time the web application is accessed.
 14. The method according to claim 13 wherein the web application includes a plurality of web pages, and further comprising inspecting the plurality of web pages until all colors in all components of the stylesheet are mapped to the source set of colors to achieve consistency over the plurality of web pages.
 15. The method according to claim 14 further comprising adjusting the colors in the selected position based on user input.
 16. The method according to claim 11 wherein the distances between the colors in the source set of colors and the distances in the replaced colors for each position are limited to adjacent colors.
 17. The method according to claim 11 wherein the respective distances are determined using at least one of the following distance determination methods: an RGB Euclidian distance method, a Cielab Delta E method, and a color tolerance distance method.
 18. The method according to claim 11 further comprising determining the source set of colors based on analyzing at least one of the following: color schemes in a source web application, color schemes in a logo, and a user defined color scheme.
 19. The method according to claim 11 wherein in response to the source set of colors being monochrome, further comprising generating variants of the monochrome colors so as to expand the source set of colors.
 20. A non-transitory computer readable medium for operating a computing system to generate a color scheme, and with the non-transitory computer readable medium having a plurality of computer executable instructions for causing the computing system to perform steps comprising: determining distances between colors in a source set of colors to be used in the color scheme; determining positions of colors in a target set of colors that can be replaced with the colors in the source set of colors; determining deltas between distances in the replaced colors and the distances in the source set of colors for the determined permutations; and selecting one of the positions to be used as the color scheme based on the deltas being minimized with respect to the deltas for the other determined positions.
